Notes 1.
Default Priority is the priority order when more than one maskable interrupt request is generated
simultaneously. 0 is the highest priority and 11 is the lowest.
2.
Basic configuration types (A) to (D) correspond to (A) to (D) in Figure 6-1.
Remark
Two watchdog timer interrupt sources (INTWDT) are available: a non-maskable interrupt and a
maskable interrupt (internal), either of which can be selected.
